Question about TaskContainer implementation

[Jeroen Breedveld <je...@x-hive.com>]

Hi all,

I've created an implementation of the TaskContainer interface for my
company's database with the purpose of running several tasks in one
(database) session.
The problem is that when I use this taskcontainer the embedded task are
not performed although I'm sure the perform() method is called on these
tasks (see output).
Can anyone tell me what I am doing wrong?

Also when I use the log method from a taskcontainer the name of the task
doesn't appear in the output (see the output) but instead "null". What's
causing this?

Best regards,

Jeroen Breedveld
